To all whom'it may camera/i- Be it known that I', HENRY AU'cnU, a citizen of the United States, residing at Emporium, county of Cameron and State 'of Penn sylvama, have invented certain new and useful Improvements in Machines for Forming 'aCartridge Ro e from Explosive Gelatin, of

which the following is a specification.

' This inventionrelates to, machines forforming a cartridge rope from explosive gelatin."' l

The manufacture of cartridges from explosive gelatin, which isa plastic substance of aconsistency depending upon various 'conditions, is generally carried on by forcin it,

under pressure, through a nozzle'from w oh the gelatin emergesas a continuous r0 e, the diameter of which may be from less t an an n inchfto upwards of two inches, this rope being cut into suitable lengths, usually about eight inches, after emergence from the nozzle, to thereby form the cartridges which are thonsuita'bly wrapped so as to be ready for commercial use. i

. Machines of the character set forth have usually employed ahorizontal' screw, termed I by skilled workers in explosives a packing screw," for forcing the explosive gelatin through the nozzle, and associated with this acking screw meanshave been employed to eed the plastic gelatin to the screw.

Heretofore in machines for forming a cartridge rope from. explosive gelatin, no means have been provided for removin the feeder, which delivers the explosive gelatin to the packing screw, from the hopperin which it operates except by taking apart the machine itself. Machmes of the character set forth have to be cleaned quite frequently, usually at the end of a days run, and for this reason, it is very desirable to provide for such cleaning Without taking the machine apart.

Theparticular object of the present inventionis the provision of means whereby the feeder may be-readily and easily removed from the hopper in which it o erates whenever it is desired to inspect or '0 can 1t, and 111 this connection-I seek to provide such 'an'ar- 'range'ment that the packing screw may contime its 0 er'ati o'n regardless of the position of the fee er, so that thefeeder and packing screw are entirely independent in-their oper--' ations.

To carryout this object I pi ovidea' novel carriagesupporting the feeder, together with novel whereby th arriage may bel raised or, lowered to remove the feeder fronr the hopper orto replace it in theho per, and

i-nthis connection there is employe an oper-.

ating device for the feeder whi'ch permits the foregoingo erations Without requiring any stoppage 0 the machine or detachment of any ofthe parts thereof.

While the present improvements areshown and described as being embodiedin a machine employing a horizontal packing screw, 1 wish it understood-that such useis not'the only one to which the invention may be put, as itis susceptible of use in other connections and-even without the employment of a separatepackingscrew.

n the present invention I haveshown cer-,

tain' other novel constructions relating to the mounting and shiftabilit'yt of the 'acking screw, the rotating meansfor the fee er, etc, which are fully set forth and claimed in other applications executed by me of even date herewith, (Serial Nos. 37 5,296 and 375,298)- and hence, no claim is laid to them herein.

The present' invention is fully set. forth hereinafter and its novel features'a're recited in the appended claims,

In the accompanying drawings: Figure 1 is a side elevation, partly in section; Fig.1, a detail of the means for adjusting the packing screw shaft and arking screw carriage;

Fig. 2, aside elevatlor of the machine, showmg the ackmg screw and its carriage re-- treated roin the packing screw case; Figs. 2 and 2", details of the bevel'gear cohperatfeeder;' Fig. 3, a front end elevation of the machines; Fig. 3, a detail of the detachable ing with the screw 'that raisesand lowers the cou ling between both packing screw and itssha t and the feeder and its shaft; Fig. 4, a rear end elevation of the machine; Fig 5, a horlzontal section. on line '5-510f F 1g. 1;

6, a detail section showing 'the lower cross-piece of the carriage which carries the feeder, Fig. 7, a detail of the movable friction wheel and its shaft; and of one of the adjustable bearingsQ The base of the machine consists of a base part 70 which su ports the packing screw case- 7, which is ofead or LBab' itt metal and is bolted to the base part 70, there being employed a tail-piece 71. The parts '70" and 7l are rigidly romiected by. parallel guide rods' 72. 'A sub-base or carriage73, which has sleeves 74 that slide on the guide-rods 72, is

8, adeta l provided with bearings 2, in which a packing screw shaft 3 is journaled, while 4 designates the packing screw, which. is of bronze, and this screw is of slightly less diameter than 5 the bore ofthe packing screw case 7 which receives it. The packing screwhas a short I shaft-section 5 which is connected by a screw-cou ling 6 with interposed rubber or paper was er 6 to shaft 3, the threads of the 10 screw-coupling being so arranged that rotation'of the packing screw and shaft 3'tends to itlghten the joint 6 In machines for pack ex losive gelatin, it has been usual to form t e packin screw :and'its complete 5 ShfiihaiiOlli a sing material when in contact with the gelatin is not adapted to cause danger by friction, but as bronze and other alloys-increase the ex- I I pense, the foregoing fil'r e ggment enables the '20 shaft 3 to be made of-steel without detracting fromthe advantages of the use of bronze for the. packing screw A'screw 11 threaded into the lug 12 and bearing against the rear I end ofshaft 3, provides means for adjusting 1 the packing screw 4 in itsj'case 7 to bring its ,tip as near as possible'to the inside of the nlozzle 8 without touching the latter, the noz- I threadedly and detacha'bly connected to the so packing screw case 7, thus permitting separation of these parts for purposes of cleanin When a nozzle is employed which has a sm ll aperture so that a small sized cartridge will be formed, it may be found advisable to ad- '35 just the? acking screw aslindicated, as the gelatin will then beforced through the-nozzle with greater facility: and the" ressure which would otherwise arise woul be relieved. Ad'ustable set collars 1 0 are em- 4'0v loyed'on s aft 3 to limit endplay thereof.

- ecured by splining or otherwise, to shaft 3, (pulleys 13 and 14, the latter being are belt I connects by belt 15 to a clutchulley 16 on a lineor countershaft 17, a hand ever 18 being provided for throwing the clutch-pulley 16 into and out of o erative engagement with shaft 17, whereby the machine maybe started orsto ed. To Slll t the sub-base, which may be 50, termed a carriage, back and forth on the rods or guides 72, a screw is employed, the same being threaded through the tail-piece 71 and having a head 76 swiveledin lug 12 so that the carriage or subbasemay be retreat- 55 ed as well as advanced. A suitable hand Wheel 7 7, carried by the screw, is used for advancing or retreating the carriage in orderv that the packing screw 4 may be inserted in its case 7 or removed therefrom for purposes io of cleaning. Toprevent too farinsertion of "screw 4 in case 7, an adjustable. screw 78 is e iuployed, ,against which carriage 73 abuts. A removable pan79 is ad tedto catch any loose particles of gelatin ailing from screw 5 4- when it is removed from its case. l

e piece ofbronze, as this eing bolted to a collar 9, which is I at one side to facilitateintroduction of the 100. Mounted u As'thus far described, the machine is sub st'antially similar to constructions set forth and claimed in other applications executed. by me of even date herewith.

Rising from and bolted to the base part 7 0 on opposite sides of the packing screw case 7, is a frame 100 having an u per cross-piece. This frame isprovided with'l i gs 101 in which are secured parallel vertical guide-rods 102. A carriage 103 has its vertical parts sleeved upon or slida-ble on the guide-rods 102, this carriage having crossieces 103 and..103 in bearings 103 of whic is fournaled a feeder shaft 27, which is held om dropping by collars 28 adjustably secured by set screws to the shaft 27 and resting upon the upper. faces of cross-pieces 103 and 103". To prevent upward movement of the shaft'27, except that very small endwise'movement such as re common with anyrotatable collared as shaft, there is secured on the shaft 27 a collar 29, which is held by a set screw. The collars 28 and 29 may be adjusted to thedesired. extent to prevent binding of the shaft 27 in its bearing. the key 33 is a friction wheel 34, the lower face of which is, by reference perfectly flat.- The feeder is of hron'ze'and comprises a shaft30 having horizontal blades or paddles. 31, which are substantially elliptical in crosssection and are disposed with their faces at an angle to the length of the shaft 30, said shaft 30 having a detachable screw-threaded coupling 32 with the lower end of shaft 27, this cou ling bein in all respects similar to .the coup ing 6 andhavinggherubber or paper gasket. -or washer betwee its parts. The hopper22 isbolted to the top of. the packing screw case 7 and the upper part of the hopper is in the form of a cylindrical ring 05 23, WlllCll is detachabl connected to the lower part thereof by t e flanges and-bolts, 24, permitting removal of the upper part for purposes of clea The ring 23 iscut out gelatin into the ho per. I

Rising from the base 1 and suitably bolted thereto is a yoke-upright 20, to which is bolted a substantially horizontal yoke-frame 21, which in turn, is bolted to the upright frame 100, thereby rigidly bracing said frame )on and connected to the oke-frame21 are caring standards 35 which ave vertically and horizontally adjustable bearings 36 made so by the four screws 36, in which is mounted a horizontal shaft 371 Splined upon the projecting end' of shaft 37 by a feather 40 carried by said shaft, is a friction wheel 39 which may, owing to? said plined connection 40, he slid lengthwise of frame-piece 21 at 42, said lever having a slot I and pin connection 41 with a shifter 41? slidable ona statio ary guide 41 and ha a fork 41 engaging a groove 41 in theiifi Rigidly secured to shaft 27 by. I l

e shaft by a hand-lever 41 pivoted to the of the wheel 39. The friction wheel 39 bears a ainst the flat under .face of the-friction w eel3f1, and asthe shaft'37 is in the same lane as shaft 27, thefriction-wh'eel34 will 5 t e driven faster or slower, according as the.

"frictionwheel 39- is moved toward or away fi'b'ln'shaft 27. The shifting of'frictio'n wheel 39 may be instantl' accomplished bythe operator, who thus as the rate of. rotation o the feeder under absolute control so that if the operator finds that the feeder is crowdingthe packing screw by feeding too much gelatinto it, or if the consistency of'the gelatin demands a different rate of feed, the oper-' with a head 106 whichi srigidly held against turning in the box 107 on the upper crosspiece 103, said box having removable parts permitting attachment and detachment of the head 1 06. Journaled in bearing standar(ls 108 on the upper cross-pieceiof frame which are fastened bevel gears- 110 and 1 1.1, u the jfornier meshing with bevel gear 105.

v *Journaled in bearings 112 on frame 100, is a shaft 113, whichhas secured to its upper end 'a bevel gear 1 14 TIilGShjllg with bevel gear 1 1 1,

whilethe lower end of this shaft has a handwheel 115 located atone side'of the packing box for case 7 inconvenient position to be turned by the operator.

. v In the operation of the machine, the feeder 40 within the hopper 2223, forces the gelatin A ,throughthe opening in the top of thepacking iscrewcase 7 and the packing screw-4 in turn, presses. the gelatin out through the nozzle 8 m' the form of a continuous cartridge ro e, whichvisnafterward severed into marketa le lengths of about. eight inches and then wrapped.

As reviously en lained, the shaft 27 is" capab e of a very s ightendwise movement' which is no greater in magnitude than is I common in an .shaft having collars to limit its endwise or engthwisethrust as some play is necessary in shafts thus held, in order to revent'binding of the collars on the bearing.

lhi's slight play,lwhi ch is only a very small .fraction of an inch, issufiicient, however, to

cause the, face of friction-wheel '34 to lift clear of engagement with friction-wheel 39,

when the pressure of the feeder upon the gelatin in the hopper becomes so great that the-reactionary effect overcomes} the com- 1 bined weight of the feeder, feeder; shaft, friction-wheel, etc., and hence the feeder will automatically stop rotating by reason of the disengagement of the frict on-wheels- 34 and out stopping the machine. raisingt is a shaft 109- to theo'p'po'siteends of 39 when thefeed becomes too great; Immediately the ressureron the gelatin is relieved somewhat, the frictionwheel :34 drops slightly and again bears on friction-' Wheel 39- andv theyfeederthen resumes its rotation.

VVhenit is desired to inspect the feeder for purposesof cleaning, it maybe lifted bodily out of the hopper by turning the hand-wheel 115, which, operation causes rotation of the bevel gear 105, which in turn, draws upon' the screw 104, lifting it, and lifting the carriage 103, shaft 27 and wheel .34, and the feeder itself, the carriage 1 03 sliding vertically on the guides 102. With this arrange ment the entire feeder, may be lifted out of -the hopper or the feeder may be only partly raised. The lifting. of the carriage 103 causes the wheel 34 to be raised out of contact with frictionwheel;39 andfthis can be done with-.-

The meahs for."

e feeder being self-locking, the carriage and feeder will remain in any osition to which they may be raised. The e evati-ng I'neans employed obviates the necessity of forming the hopper insections unless it is desired to do so. .The en 'a'gement of the wheels 34 and 39, whengthe eeder is lowered, prevents the lower end of the feeder from striking the packing screwfor the addles 5 from striking the interior of the opper, thereby rendering lowering of "the feeder entirely safe.
